Data Manipulation

Provides utility functions for checking data types and manipulating data. For example, the `isString` function can be used to check if a variable is a string.

import { isString } from '@sentry/utils';

function logMessage(message) {
  if (isString(message)) {
    console.log(message);
  } else {
    console.log('Not a string');
  }
}

Environment Checks

Includes functions to check the current runtime environment, such as whether the code is running in a browser or Node.js environment. This is useful for writing isomorphic code that runs both on the client and server.

import { isNodeEnv } from '@sentry/utils';

if (isNodeEnv()) {
  console.log('Running in a Node environment');
} else {
  console.log('Not running in a Node environment');
}

Integration Helpers

Provides functions and classes to help integrate with Sentry, including adding global event processors that can modify or filter events before they are sent to Sentry.

import { addGlobalEventProcessor } from '@sentry/utils';

addGlobalEventProcessor(event => {
  // Modify the event object or return null to skip sending the event
  return event;
});
